Another unusual grey

Back in July, I posted about an unusual grey Connemara stallion (Ponies don’t read). There I linked to two unusual grey Iberians, Comico IV and Comico VI. Recently someone sent me a link to the stallion in the video above. He is Favacho Único, a Mangalarga Marchador from Brazil. His resemblance to the two Comico horses is striking.

Many wanted to call Comico IV a rabicano. I think the dramatic white tail head (pictured here) was what gave people that impression. In the video of Único, that same trait is very noticeable. It can also be seen in the photo of him on the farm’s website. The concentration of the white on the face and legs is also very similar to the Comico horses.

He does have a grey parent, and he does have grey offspring, although whether the color came from him or not is not immediately clear. Grey is a common color in that particularly bloodline, so ruling the stallion in or out as the source is difficult. It is clear that whatever is going on with his greying, it was progressive. He is presently 27 years old. Here is a video of him as a younger horse.

That is an extreme amount of greying for a horse that, while definitely older, isn’t truly ancient. Still, it is even more unusual for a grey horse to look so dark so late in life. That could have been said for the Comico horses as well. They are certainly oddities!

Whatever it is, there are more horses like him among the Herdade horses, the bloodline that produced Único’s sire. This is Herdade Cadillac. Here is the dam of Herdade Cadillac, Herdade Alteza. The sire of Único, Herdade Teatro, is a paternal half-brother to Cadillac. Notice these horses the same concentration of greying on the face and legs. The stallion, Cadillac, even has the same kind of irregular white spots on the body that can be seen on Único. Finding it within a family like that suggests that there is some kind of genetic component. It would be interesting to test the horses (those still living) to see if they are genetically grey. If that is the case, then it would seem that there is some kind of modifier at work that changes the way the greying progresses.

Spotted Arabs and Barbs


In a previous post, I included this Currier & Ives print when talking about how nineteenth century horsemen often associated spotting patterns – pinto or appaloosa – with oriental horses. Their role in circuses, accompanied by handlers with fanciful costumes, probably did a lot to set this idea in the minds of many. It wasn’t just the general public, though. The earliest American stud books often contain references to “spotted Arabian” ancestors. Alexander, the horse pictured in the print, was himself entered into the American Stallion Register.

ALEXANDER, spotted, black and white, 15-3/4 hands, 1200 pounds; foaled about 1822. Owned by Page’s circus, who purchased him in the West, and sold him about 1831 for $1000 to a company at Middlebury, Vt. Advertised, 1833, at Middlebury and Vergennes, Vt., by S. H. Baker for the owners. Terms, $7 to $10. In 1836 Harvey Yale of Middlebury bought one half interest in him, and had charge of him two seasons, one of which he was kept at Hancock, Vt., by Mr. Church. Mr. Yale sold him to Mr. Twilight, Vershire, Vt.

Mr. Yale, in an interview, 1885, said: ” Alexander was a large horse with spotted color, and called a Spanish horse. He weighed about 1200 pounds. His true breeding was not known. A company at Middlebury bought him of a circus company at Rutland. Hough made the trade. He was a good-looking horse, very intelligent, and a good roadster, but his stock varied, and took a long time to come to maturity. Some had light manes and tails.”

Sire of dam of Gray Eagle (Earing’s), and 2d dam of Benedict Morrill.

In that entry, he is referred to as a Spanish horse, not an Arabian or other oriental breed as his advertisement might suggest. It may be that the circus later changed his background story, or they may simply have conflated the term Barb with Arabian. Although modern horsemen think of those as being opposites, during the time Alexander was alive the terms were often used interchangeably.

It was situations like this that were behind the original prohibitions against spotting in the American Arabian registry. That organization was a relative late-comer among American stud books, so it had close to a century of misinformation about its breed to overcome. It is pretty clear that the horses the founders had in mind were the tobianos and the leopards like Alexander, and not the sabinos that really were found in the population. Unfortunately overturning the white rule took a long time, because the reaction to the misinformation created its own misunderstanding of the true nature of Arabian coloring. Instead of “Arabians are never spotted like that”, people became convinced that “Arabians are never spotted.”

But for a time, many American breeders thought horses like Alexander showed their blood-horse origins with their coloring. The colors themselves had largely fallen out of favor at that point, but their presence in the back of the pedigree did not raise eyebrows the way it certainly would today. It is not just the American Stallion Register, either. There are “spotted Arabians” listed in the backs of pedigrees in most of the American light horse stud books from that era. Undoubtedly many were pintos, but the fact that some may have been leopards like Alexander leads to an interesting question. Just how many American light breeds carry hidden patterning genes?

The two horses listed as descendants of Alexander, Gray Eagle and Benedict Morrill, also appear in the first volume of the Morgan stud book. Neither was described as spotted, but the leopard pattern gene isn’t visible without the leopard complex (Lp) gene to activate it. Alexander would have had Pattern1, since he was a leopard, and he could have passed it along to his offspring. This is also true for any of his daughters that were used, but not recorded, in the backs of pedigrees, as well as any other leopard patterned horses found during that time. It is pretty clear that almost as soon as the stud book movement got off the ground, odd colors were systematically eliminated among finely bred horses. In the case of some of the appaloosa patterns, though, the component necessary for the louder parents could have remained among those horses that did not get Leopard Complex .

Someday testing may allow breeders to check solid horses for the presence of these hidden genes. If pattern genes are found, they might just come from some of these “spotted Arabians”.
